Question

Example 10.1
A convex mirror used for rear-view on an automobile has a radius of curvature of 3.00 m. If a bus is located at 5.00 m from this mirror, find the position, nature and size of the image.​

Answer 1

Explanation:

F = 1/2* Radius of curvature

F = 1/2*3

F = 3/2

u = -5 cm

using mirror formula

1/f = 1/v + 1/u

1/3/2 = 1/v -1/5

2/3 + 1/5 = 1/v

1/v = 10+3/15

1/v = 13 /15

v = 15/13

therefore its position is between Pole and infinity

nature of the image is virtual errect

size = diminished and wider field of view
